Purpose of change

This adds a profession to post-apoc-focused scenarios aimed towards showcasing the content added in #5466.

Describe the solution

1. Added a monster hunter profession, a SCEN_ONLY profession that starts with appropriate innawoods gear along with a full set of scaleskin armor, a stinger dagger, composite shortbow, and two quivers to choose between tooth arrows or stinger arrows depending on the situation. Non-combat skills aim to be exactly enough to make all the items they spawn with and any components needed to make those.
2. Added the new profession to Next Summer, Ambushed, and for flavor Mi-go challenge (since rescuer profession similarly is dressed in furs and has post-apoc getup, and the scenario is quite lacking in profession options currently).
3. For flavor, added to Dinomod's surrounded by dinos scenario.

Describe alternatives you've considered

Going for more of a wasteland barbarian style for the profession, making them more melee-focused and favoring the bone club or the leiomano. Maybe if in the future I re-implement bone armor (which will likely favor heavy bones) then that can be a melee-focused foil to this profession.

Testing

1. Looked at recipes for items in the new profession's inventory to confirm it was all stuff their current skill spread allows them to make.
2. Checked affected files for syntax and lint errors.
3. Load-tested in compiled test build, confirmed the profession looked right.
4. Loaded up a world with Dinomod added, confirmed the change to the scenario didn't mess with it inheriting the default profession list.

Additional context

Obligatory @LyleSY ping since this touches something in Dinomod too.
